Background:
Gingiva is a keratinised mucosa akin to the skin and is exposed in all modalities of treatment of oral cancer. Acquired lymphangiectasia are acquired dilatations of lymphatic channels secondary to an external cause. They are extremely rare in the oral cavity despite that oral cancers are treated with different treatment modalities.
Methods:
The archives of the Oral and Maxillofacial Pathology Department of our institute were retrospectively reviewed from 2001 to 2021. Of the 9566 cases of oral biopsies, 4596 were confirmed cases of oral cancer including salivary gland carcinoma. These cases were followed up for the presence of post-neoplastic and post-therapeutic gingival lesions.
Results:
Of the 4596 patients, <10% patients reported recurrence or new primary of squamous cell carcinoma in the gingiva. Two patients were histopathologically diagnosed with acquired lymphangiectasia of gingiva after 12 years following surgery and radiation therapy as treatment for oral squamous cell carcinoma and mucoepidermoid carcinoma, which has been described in our report for the first time in the literature.
Conclusion:
Even though acquired lymphangiectasia of gingiva is very rare, lymphatic malformations should be included in the clinical differential diagnosis of post-therapeutic gingival proliferative pathologies in order to ensure appropriate treatment and prevent over-diagnosis of this benign condition.
